Parallelograms on same base and same parallel lines are equal in area
Step-by-step explanation:
Construction - Join BG
Parallelogram AEFG and ΔABG lie on same base AG & between parallel lines AG & EF.
So,
ar ΔABG = (ar AEFG) ""(1)
Parallelogram ABCD and ΔABG lie on same base line AB & between same parallel lines AB & CD
So,
ar ΔABG = (ar ABCD) ""(2)
From equations (1) & (2) -
ar AEFG = ar ABCD
This Proves that Parallelograms on same base and same parallel lines are equal in area
